The Utilization of Silica–Lignin Composite as a Green Adsorbent for Cobalt and Lead Metal Ions in Aqueous Phase

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Heavy metals in environmental waste can pollute the environment and disrupt human health if not managed properly. Heavy metal contamination from industrial waste, particularly cobalt (Co) and lead (Pb), poses serious environmental and health risks due to their toxicity, persistence, and bioaccumulative nature.

PLA/WOOD BIOCOMPOSITES: IMPROVING COMPOSITE STRENGTH BY CHEMICAL TREATMENT OF THE FIBERS [PDF]

, 2013
A resol type phenolic resin was prepared for the impregnation of wood particles used for the reinforcement of PLA. A preliminary study showed that the resin penetrates wood with rates depending on the concentration of the solution and on temperature ...

Biopolymer‐Coated Paper Composites for Sustainable Packaging

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Conventional plastic packaging, though dominant in food and flexible applications, poses serious environmental concerns due to its persistence and limited recyclability. To address this challenge, this study develops bio‐based coated paper composites as sustainable alternatives. Paper, while biodegradable, lacks adequate barrier properties. To

Improving Oxygen Barrier Performance of Polylactide Film by Using Bleached and Unbleached Nanocellulose From Grape Pomace

Journal of Applied Polymer Science, EarlyView.
Bleached and unbleached nanocelluloses were produced from the exhausted grape pomace and applied as coatings on PLA substrates for sustainable food packaging. Unbleached nanocelluloses were more hydrophobic and amorphous than bleached ones. The resulting bio‐based bleached nanocellulose‐coated PLA films showed a 68% reduction in O2 permeability ...
